    ... And aircraft running on an ammonia-fuel cell powertrain dont have to, and probably will not, look very much like jet air planes at all, because the primary consideration becomes turning electricity into airflow as efficiently as possible...
  • Commented on 2117 revisited
    Sails are still terrible at keeping schedules. This means any trade that relies on them must not be time critical, and needs serious warehouse space at both ends to buffer the supply chain. The last bit gets quite expensive. And...

    .. Salted soil is not solved by genetic engineering, it is solved by Civil engineering. Specifically, either building your irrigation and drainage systems correctly in the first place, or by coming in after and fixing the mess. This is another...
  • Commented on The sudden eruption of news
    This is also why it is so very attractive as a fuel - No limits on how much can be produced, no footprint on the biosphere at all because the cycle starts with nigh-limitless resources and the end point returns...
  • Commented on The sudden eruption of news
    ..The methane is used as a cheap source for hydrogen. Decarbonizing ammonia production does not require a clean source of methane, it just needs a clean source of electricity, because the hydrogen can be gotten from electrolysis just as easily....

    And if physically feeble.. Uhm. I expect the medical profession to get a lot more.. open handed with various interventions to get people into shape. Your piss may be an interesting shade of blue, but you havent felt this good...
  • Commented on 2117 revisited
    Retraining also is a problem that can be solved by throwing more labor at it. Most of the doom scenarios seem to envision everyone just.. sitting on their asses and dying without trying to solve any of it. Which is...
  • Commented on 2117 revisited
    One thing: The next century will have a lot of labor to throw at problems. Oceans of it. Seen from a certain perspective "Automation making many jobs obsolete" and "Climate change and other disasters" are a nail and a hammer....
  • Commented on 2117 revisited
    A hundred years of biotech is a long time. I am really uncomfortable saying anything is not going to be both doable and routine in that timeframe unless it blatantly violates physical laws. And a placenta that isn`t inside a...

    Change: The Flynn Effect, 2.0 For a long time, it has been noted that iq tests need adjusting because the average person gets better at them over time. This is mostly chalked up to things like iodine in salt, better...
  • Commented on The internet of decay
    Market segmentation, then regulation. Someone is going to go to the effort of writing firmware for most of the functionalities you want networked to "Proven Correctness" standards. ... Uhm. I think I have a startup idea now. Exuse me while...
  • Commented on Some notes on the worst-case scenario
    The biggest thing is that renewable energy run for energy production rather than for warm fuzzies is about locality, locality and locality. The efficiency of long distance power transmission is a great deal better than that of batteries. If you...
  • Commented on Policy change: future US visits
    It's mystery cult social engineering as a mass communication tool - Shodan obfuscates their points so that understanding them incurs a sunk cost of effort, which makes recipients that expended that effort take them somewhat more seriously. That or just...
  • Commented on Policy change: future US visits
    Reading that, the bay has.. extremely impressive mechanisms for oxygen transport into the deep waters. This isn't the baltic. I'm kind of boggled it's even possible to overload them, but then I looked at just how many people live next...
  • Commented on Policy change: future US visits
    Ten billion is perfectly managable for the long haul. Far more so than the sort of chaos a gigadeaths would imply. People do not go quietly into the night - if there really is a plan to engineer famines, that's...
  • Commented on Policy change: future US visits
    .. Iron fertilization is only a sensible move in the high ocean low productivity zones. Anoxia is a product of low mixing of the deep waters, excessive nutrient runoff from agriculture and insufficient filterfeeders. All of those are attackable problems,...
  • Commented on Policy change: future US visits
    That is just wrong as a matter of fact - even in california, which has absurdly expensive electricity and very cheap gasoline, the savings on fuel cost are very high - roughly a factor of four. - Now, airlines are...
  • Commented on Policy change: future US visits
    It can, and will, pop very abruptly through technical obsolescence. The personal electronics industry is pouring billions into better batteries every year. From the perspective of manufacture and logistics, then given sufficiently good batteries electric automotion is strictly better than...
  • Commented on And the Rabid Nazi Raccoons shall inherit the Earth
    RE: Low weight reactors for space use, and high performance drives.. You can have both. May blow up spectacularly, but there is this very neat paper design if you can get people to sign off on grinding a few dozen...
  • Commented on "You're only supposed to blow the bloody doors off!" 2017 continued.
    Gotta agree with the "Too complicated, Big hammer" school of testing. But that's mostly because I'd never buy gold with the intent of leaving it in bar form anyway. It's a useful - and beautiful - material, and I don't...
  • Commented on And the Rabid Nazi Raccoons shall inherit the Earth
    ... I'm thinking in terms of personally surviving the next millennium. And your plan sucks. It sucks in terms of descendant survival too - existence is not an unconditional good. If your plan for the future involves your children and...
  • Commented on And the Rabid Nazi Raccoons shall inherit the Earth
    No, no. What you want is a place with stable geology, a coastline consisting of cliffs, and navigable water. And either a solid solar resource or reactors. Black Flag City, aka, Fata Morgana, the City of Mirrors and stone. There's...
  • Commented on And the Rabid Nazi Raccoons shall inherit the Earth
    The lot of you are not being nearly bloody-minded enough. If black-flag regions and mass migrations happen, you set up a micro-climate in the equatorial deserts with mirrors-shades, solar cells and evaporators - Ain't nobody going to bother your industrial...
  • Commented on "You're only supposed to blow the bloody doors off!" 2017 continued.
    You're committing enumeration. It's a common fallacy - human intuition fails very badly with very small and very large numbers, which means you will nearly always overestimate the cost or impact of something if you split the description of it...

    .. Which is down to their plan to substitute tourist income for their declining oil revenue. which.. Okay, on the one hand, I can see why they want to do that. On the other.. hand.. The island of Lesbos has...

    Or use it industrially, of course. It has uses....

    This is true for aluminum, and for some designs, but there are steel smelters that are currently run entirely on off-peak power due to cost of electricity savings, so running them only in the day isn't a problem. Arc furnace...
  • Commented on "You're only supposed to blow the bloody doors off!" 2017 continued.
    Low-probability events are one thing - it can be perfectly rational to just go "Preparing for all of them is going to cost more than just doing damage control after the fact on the ones that actually happen". It's failing...

    Steel production per metric tonne via electricity: 440 kwh. (the mines are often as not electric anyway, because it saves on ventilation) Cost of solar electric in a greater than 2000 wh/m2 insulation location (equatorial desert), what, 5 cents? so.....
  • Commented on "You're only supposed to blow the bloody doors off!" 2017 continued.
    Somewhat. In the sense that I do a google sweep every six months on whats happening with a list of technologies, including desal. The middle east is doing *some* desal. The more functional parts. But.. they could be having an...
